May ordinary general-purpose equipment be installed where flammable vapor classification requires identified equipment?
- AYes; if the breaker is larger
- BNo; all electrical equipment is prohibited in every classified area
- CYes; if painted red
- No; use equipment suitable for the classification
Why D is correct
Classified-location rules manage ignition risk through equipment, sealing, wiring methods, and installation practices matched to the material and division or zone. Ordinary equipment is not made suitable by paint or breaker size.
